The MT ID3 STX has three available power sources: the internal battery, an external battery, and AC power. Fast update rates for filling make them ideal for use in process applications or for simple weighing. The ID3sTx terminal incorporates "smart" features as well, including ID, time and date fields that allow you to identify transactions or part numbers; a programmable sleep mode that extends battery life and reduces maintenance; and special calibration steps that eliminate the non-linear effects of certain load cells.
